From: Claudiu Beznea <claudiu.beznea@microchip.com>

[ Upstream commit 267ad94b13c53d8c99a336f0841b1fa1595b1d0f ]

Pointers from synth_clock_names[] should be freed at the end of probe
either on probe success or failure path.

Fixes: b7bbf6ec4940 ("clk: si5341: Allow different output VDD_SEL values")
Fixes: 9b13ff4340df ("clk: si5341: Add sysfs properties to allow checking/resetting device faults")
